Question

spillting the middle term x²-7x-30​

Answer 1

Answer:

Given to factorise:-

x²-7x-30

Solution:-

x²-7x-30

Product= -30

Sum= -7

Numbers= -10,3

Splitting the mid term:-

x²-10x+3x-30

x(x-10)+3(x-10)

=(x+3)(x-10)

If it's quadratic equation:-

x²-10x+3x-30=0

x(x-10)+3(x-10)=0

(x+3)(x-10)=0

x+3=0 or x-10=0

x= -3,10
